Studies in class structure.

Of the six studies which make up this volume, four
have been published previously -two in English and
two in French. (I) Introductory' is new. (II) "The
Influence of Technological Changes on the Development of
Class Structure in the Western World' appeared in French in
the Belgian periodical Industrie in April, 1953. It has not been
published until now in English. (1II) "The Social Structure
of England' appeared in two articles in History To-day in
F'ebruary and March, 1951, but has been revised for pub-
lication in this volume. (IV) "The Conception of the Middle
Classes was originally read as a paper at the Anglo-French
Historical Congress held at All Souls College, Oxtord, in
September, 1949, and was subsequently printed in the
British Journal of Sociology in December, 1950. (V) Elites in
British Society' was originally written as a contribution to a
projected volume, to be published in French, dealing with
the nature of élites in various European societies; but throughh
a chapter of accidents this volume has not yet appeared, and
the essay is now published for the first time. Finally, (VI)
British Class Structure in 1951 was published in French in
Cahiers Internationaux de Sociologie in its double issue of January
to June, 1954, but is here published for the first time in
English. To the editors of the periodicals concerned I make
due acknowledgement for their consent to my use of these
articles, which were from the first intended to form parts of a
collected volume of studies.
